The study of networks, including computer networks, social networks, and biological networks, has attracted enormous interest in recent years. The rise of the Internet and the wide availability of inexpensive computers have made it possible to gather and analyse network data on an unprecendented scale, and the development of new theoretical tools has allowed us to extract knowledge from networks of many different kinds. The study of networks is broadly interdisciplinary and developments have occurred in many fields, including mathematics, physics, computer and information sciences, biology, and the social science. This text brings together the most important breakthroughts in each of these fields and presents them in a unified fashion, highlighting the strong interconnections between work in different areas

Networks and Network Analysis for Defence and Security discusses relevant theoretical frameworks and applications of network analysis in support of the defence and security domains. This book details real world applications of network analysis to support defence and security. Shocks to regional, national and global systems stemming from natural hazards, acts of armed violence, terrorism and serious and organized crime have significant defence and security implications. Today, nations face an uncertain and complex security landscape in which threats impact/target the physical, social, economic and cyber domains. Threats to national security, such as that against critical infrastructures not only stem from man-made acts but also from natural hazards. Katrina (2005), Fukushima (2011) and Hurricane Sandy (2012) are examples highlighting the vulnerability of critical infrastructures to natural hazards and the crippling effect they have on the social and economic well-being of a community and a nation. With this dynamic and complex threat landscape, network analysis has emerged as a key enabler in supporting defence and security. With the advent of 'big data' and increasing processing power, network analysis can reveal insights with regards to structural and dynamic properties thereby facilitating greater understanding of complex networks, their entities, interdependencies, vulnerabilities to produce insights for creative solutions. This book will be well positioned to inform defence, security and intelligence professionals and researchers with regards to leading methodologies and approaches.

What are organizations? Where do they come from? How are they transformed and adapted to new situations? In the digital age and in the global network society, traditional theories of the organization can no longer answer these questions. Based on actor-network theory, this book explains organizations as flexible, open networks in which both human and non-human actors enter into socio-technical assemblies by constantly negotiating and re-negotiating programs of action. Organizations are not macro social structures or autonomous systems operating behind the backs of individuals. Instead, they are scalable actor-networks guided by network norms of connectivity, flow, communication, participation, authenticity, and flexibility.

Social relations are crucial for understanding diverse economic actions and a network perspective is central to that explanation. Simple exchanges involving money, labor, and commodities combine into complexly connected systems. Economic networks span many levels of analysis, from persons (consumers, employees), to groups (households, workteams), organizations (corporations, interest groups), populations (industries, markets) and the rapidly expanding global economic system.David Knoke blends network theories from a range of disciplines and empirical studies of domestic and international economies to illuminate how economic activity is embedded in and constrained by social ties among economic actors. Social capital, in the form of connections to others holding valuable resources, is vital for finding a job, buying a car, creating a new industry, or triggering a global financial crisis. In nontechnical terms the author explicates the core network concepts, measures, and analysis methods behind these phenomena. The book also includes many striking network diagrams to provide visual insights into complex structural patterns.This accessible book offers an invaluable critique for both undergraduate and graduate students in economic sociology and social network analysis courses who seek a better understanding of the multifaceted economic webs in which we are all entangled.

"Networks are everywhere, from the Internet, to social networks, and the genetic networks that determine our biological existence. Illustrated throughout in full colour, this pioneering textbook, spanning a wide range of topics from physics to computer science, engineering, economics and the social sciences, introduces network science to an interdisciplinary audience. From the origins of the six degrees of separation to explaining why networks are robust to random failures, the author explores how viruses like Ebola and H1N1 spread, and why it is that our friends have more friends than we do. Using numerous real-world examples, this innovatively designed text includes clear delineation between undergraduate and graduate level material"--Page [4] of cover

Today, interest in networks is growing by leaps and bounds, in both scientific discourse and popular culture. Networks are thought to be everywhere - from the architecture of our brains to global transportation systems. And networks are especially ubiquitous in the social world: they provide us with social support, account for the emergence of new trends and markets, and foster social protest, among other functions. Besides, who among us is not familiar with Facebook, Twitter, or, for that matter, World of Warcraft, among the myriad emerging forms of network-based virtual social interaction? It is common to think of networks simply in structural terms - the architecture of connections among objects, or the circuitry of a system. But social networks in particular are thoroughly interwoven with cultural things, in the form of tastes, norms, cultural products, styles of communication, and much more. What exactly flows through the circuitry of social networks? How are people's identities and cultural practices shaped by network structures? And, conversely, how do people's identities, their beliefs about the social world, and the kinds of messages they send affect the network structures they create? This book is designed to help readers think about how and when culture and social networks systematically penetrate one another, helping to shape each other in significant ways.
